空天飞机欲霸太空 空天飞机是一种以液氢为燃料、采用航空喷气发动机和火箭发动机两种推进系统的水平起飞、可以自由跨越大气层往返于天地之间的大型航天器。空天飞机可由零高度直达200公里以上绕地球轨道高度,最高速度可达3万公里/小时,其起降不受“发射窗口”、天气和地点的限制,不需要规模庞大设备、复杂的航天发射场。 空天飞机的最大特点是:既可作为载人航天器,又可无人驾驶入轨与空间站对接;既可作为太空作战平台,又可从事大量的太空侦察活动。在未来太空战场上,空天飞机将发挥出重要的作用:一是可以利用其高效能的武器系统,遂行战略轰炸、侦察、截击等任务;二是可将大而重的有效载荷送入地球轨道,如将空间站、天基武器系统所需的大型构件运往太空轨道,并进行组装等;三是可以对轨道上运行的空间站或其他航天器
Space Shuttle The Space Shuttle Skyrock is a large spacecraft that takes liquid hydrogen as fuel, takes off at two levels of propulsion system of jet engine and rocket engine and freely crosses the atmosphere between heaven and earth. The space plane can reach the altitude of more than 200 kilometers from zero at altitude orbit at a maximum speed of 30,000 km / h. Its launch and landing are not limited by “launch window”, weather and location, and do not require large-scale equipment and complicated spacecraft Launch site. The most prominent feature of the space plane is that it can be used as a manned spacecraft and can be docked with the space station without driver's hand. It can be used as a space combat platform and a large number of space reconnaissance activities. In the future space battlefield, the space shuttle will play an important role: First, it can use its high-performance weapon system to carry out such tasks as strategic bombing, reconnaissance and interception; and second, it can send large and heavy payloads into the earth Orbit, such as the space station, space-based weapons systems required large components transported to space orbit, and assembly, etc .; third is the orbital space station or other spacecraft
